video: goldfishfb: fix memory leak on driver remove
[ Upstream commit 5958fde72d04e7b8c6de3669d1f794a90997e3eb ]
goldfish_fb_probe() allocates memory for fb, but goldfish_fb_remove() does
not have deallocation of fb, which leads to memory leak on probe/remove.
The patch adds deallocation into goldfish_fb_remove().
Found by Linux Driver Verification project (linuxtesting.org).
